Synopsis
=======
A vulnerability in Babel could result in remote code execution.

Background
=========
Babel is a collection of tools for internationalizing Python
applications.

Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-python/Babel < 2.9.1 >= 2.9.1

Description
==========
Babel does not properly restrict which sources a locale can be loaded
from. If Babel loads an attacker-controlled .dat file, arbitrary code
execution can be achieved via unsafe Pickle deserialization.

Impact
=====
An attacker with filesystem access and control over the locales Babel loads can achieve code execution.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All Babel users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">Þv-python/Babel-2.9.1"
